NHS Missed Appointments

Patients miss NHS appointments for many reasons. Some forget, particularly when appointments are booked far in advance. Others receive letters late, misunderstand appointment details, or struggle to contact the right team when they need to cancel or rearrange.

Practical barriers also matter. A patient may be unable to get time off work, find affordable transport, arrange childcare, or travel safely because of illness, disability or anxiety. Some people may be digitally excluded, while others may rely on carers, family members or community transport. For children’s services, NHS England notes that missed appointments are often referred to as “was not brought”, reflecting that attendance may depend on adults and wider circumstances rather than the child.

Communication problems between services can add another layer. Patients may receive several NHS appointments close together, at different sites, or in sequences that are impossible to manage. One team may not see what another has booked. A patient may be expected to attend a diagnostic test in one location and a consultation elsewhere with little time in between. These are not failures of intent. They are signs of appointment systems that do not always work around real life.

The cost of missed NHS appointments is measured in more than money. A DNA can mean a clinician’s time is not used as planned, another patient waits longer, and administrative teams spend more time rebooking, chasing, explaining and updating records.

Financially, the impact is significant. NHS England previously estimated that more than 15 million general practice appointments were missed each year, with each appointment costing an average of £30 and the total cost to the NHS exceeding £216 million. NHS England estimated that patients did not attend 16 million GP appointments in 2025, equivalent to 1 in 23 appointments, or 4.3%.

So, how much do DNAs cost the NHS? The exact answer depends on the type of appointment, specialty, staffing model and whether the slot can be reused at short notice. But the broader point is clear: missed NHS appointments create avoidable waste in a system where capacity is precious.

Traditional appointment processes often rely on letters, one-way communication and fragmented systems. For many patients, this creates uncertainty. They may receive information through the post but have no simple route to confirm, ask questions, cancel, or rearrange. If the appointment is no longer suitable, the burden is often on the patient to find the right phone number and call during working hours.

Late letters remain a practical risk. Healthwatch England has highlighted that delayed NHS letters can mean patients miss important appointment information, test results or last-minute changes, with consequences for patient safety and care delivery.

Fragmentation is another challenge. Trusts, community services, primary care teams and diagnostic providers may use different systems, with limited visibility across pathways. Staff may not have the real-time information they need to spot clashes, identify repeated DNAs, or understand whether a patient is struggling with access.

This makes it harder to personalise reminders or support. A standard reminder may work well for one person and fail completely for another. Some patients need a text message. Others need a phone call, translated information, an accessible format, or a reminder sent to a carer.

Smarter technology does not mean replacing human care with automation. In the context of NHS appointments, it means using digital tools to make the system easier for patients and less burdensome for staff.

That could include SMS, WhatsApp, email or app-based reminders. It could mean two-way messaging that allows patients to confirm, cancel or request to rearrange without waiting on hold. It could involve automated reminders triggered by appointment type, patient preference or previous behaviour. It could also mean integration with electronic patient records, scheduling systems and patient portals, so information moves with the patient rather than sitting in separate silos.

NHS England guidance already positions digital solutions such as patient portals as a key enabler for reducing DNAs, because they can help patients access and share information, free up clinical and administrative time, and support people to take a more active role in their care. The same guidance says providers should, as a minimum, use appointment reminders such as SMS and offer an easy option to cancel or rearrange.

The word “easy” matters. A reminder that tells a patient what to do but gives them no practical route to act is only half a solution. Smarter appointment management should reduce friction at the exact moment a patient realises they cannot attend.

Technology can reduce DNAs by helping patients understand, remember and manage their appointments. This starts with clear communication: date, time, location, clinician or department, appointment purpose, preparation instructions, and what to do if the patient cannot attend.

It continues with timely reminders. NHS England’s 2026 “Tap the NHS App” campaign highlighted that nearly 1 in 4 people surveyed had missed an NHS appointment because they forgot or arrived too late. It encouraged patients to turn on NHS App notifications so they could receive reminders and rearrange appointments they could not make.

Smarter systems can also help services act earlier. If a patient cancels digitally, the slot can be offered to someone else sooner. If several patients in a particular area regularly miss appointments because of transport barriers, teams can investigate whether appointment times, locations or communication methods need to change. If a patient has a history of DNAs, the right response may not be a warning letter. It may be a call from a care coordinator to understand what support is needed.

This is where digital transformation becomes human-centred. The value is not in the software itself. It is in giving staff better information and giving patients more workable choices.

Smarter software is not a panacea. If digital appointment systems are poorly designed, they can widen inequalities rather than reduce them. Patients without smartphones, reliable internet, digital confidence, accessible formats or English-language fluency must still be able to manage appointments safely.

Privacy and trust are equally important. Patients need to know how their information is used, who can see it, and how communication preferences are managed. Messaging about sensitive services must be handled carefully, particularly where patients share devices or live in unsafe circumstances.

Interoperability is another major issue. Many NHS organisations still work with complex legacy systems. New appointment technology needs to integrate with existing scheduling, EPR and reporting tools, rather than creating another disconnected platform for staff to manage.

Staff adoption also matters. Frontline teams need tools that reduce admin, not add to it. A system that looks efficient on paper but creates extra clicks, duplicate data entry or unclear workflows will struggle to deliver meaningful change.

A better approach to NHS appointments would be flexible, joined up and patient-centred. Patients would receive clear information in the format they prefer. They would be able to cancel or rearrange quickly. Services would have enough visibility to reduce clashes, understand access barriers and reuse cancelled slots wherever possible.

For NHS leaders, success should not be measured only by lower DNA rates. It should also include better patient experience, reduced administrative workload, improved slot utilisation, fewer avoidable delays, and greater confidence among staff that appointment systems support care rather than complicate it.

The aim is not to control patients. It’s to make the NHS easier to use.

NHS missed appointments are a real and costly problem, but they are often preventable. Many DNAs happen because people forget, receive information too late, cannot travel, cannot contact the right team, or face appointment schedules that do not reflect daily life.

Smarter technology can help, but only when it is designed around patients and frontline teams. Reminders, two-way messaging, easier rescheduling, better system integration and real-time data can all reduce friction. Used well, these tools help protect clinical time, support waiting list recovery, and make care more accessible.

Reducing DNAs is not about blaming patients for missed NHS appointments. It is about recognising that people are more likely to attend when the system is clear, connected and compassionate.
